VENT-FREE NATURAL GAS RADIAN'I FLAME HEATER
AIR FOR
COMBUSTION AND
VENTILATION
WARNING: This heater shall
not beinstalled Inaconfined space
or unusually tight construction
unless provisions are provided
for adequate combustion and ven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
Today's homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduce heat loss inhomes. Home owners
weather strip and caulk around windows and
doors to keep the cold air out and the warm air
in. During heating months, home owners
want their homes as airtight as possible.
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
Fuel Gas Code. NFPA 54/ANS Z223.1, Sec-
tion 5.3, Air for Combustion and Ventila-
tion.
All spaces in homes fall into one of the three
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 6 through 8 will
help you classify your space and provide
adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and win-
dows may provide enough fresh air for
combustion and ventilation. However, in
buildings of unusually tight construction,
you must provide additional fresh air.
Unusually tight construction is de-
fined as construction where:
a°
Exhaust fans, fireplaces, clothes dryers, and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This b.
will insure proper venting of vented fuel-
burning appliances. g.
walls and ceilings exposed to the
outside atmosphere have a con-
tinuous water vapor retarder with
a rating of one perm (6x10 "11kg
per pa-sec-m =)or less with open-
ings gasketed or sealed and
weather stripping has been
added on openable windows and
doors and
caulking or sealants are applied
to areas such as joints around
window and door frames, be-
tween sole plates and floors, be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tions for plumbing, electrical, and
gas lines, and at other openings.
If your home meets all of the three
criteria above, you must provide ad-
ditional fresh air° See Ventilation Air
From Outdoors, page 8.
If your home does not meet all of the
three criteria above, proceed to Deter-
mining Fresh-Air Flow for Heater
Location, page 7.
Confined and Unconfined Space
The National Fuel Gas Code (ANS Z223. l,
1992 Section 5.3) defines a confined space
as a space whose volume is less than 50
cubic feet per 1,000 Btu per hour (4.8 m3per
kw) of the aggregate input rating of all
appliances installed in that space and an
unconfining space as a space whose volume
is not less than 50 cubic feet per 1,000 Btu
per hour (4.8 m3per kw) of the aggregate
input rating of all appliances installed in that
space. Rooms communicating directly with
the space in which the appliances are in-
stalled*, through openings not furnished
with doors, are considered a part of the
unconfined space.
This heater shall not be installed in a con-
fined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
*Adjoining rooms are communicating only
ifthere are doorless passageways or ventila-
tion grills between them.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Confined or Unconfined Space
Use this worksheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between
the rooms.
1. Determine the volume of the space (length x width x height).
Length x Width x Height = cu. ft. (volume of space)
Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)
If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of
the space.
2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.
(volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. =51.2 or 51,200 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free heater Btu/Hr
Gas water heater* Btu/Hr
Gas furnace Btu/FIr Example: Gas water heater 30,000 Btu/Hr
Vented gas heater Btu/Hr Vent-free heater + 28,000 Btu/Hr
Gas fireplace logs Btu/Hr Total = 58,000 Btu/Hr
Other gas appliances* + Btu/Hr
Total =Btu/Hr
* Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.
4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.
Btu/Hr (maximum the space can support)
Btu/Hr (actual amount of Btu/l-lr used)
Example: 51,200 Btu/Hr (maximum the space can support)
58,000 Btu/Hr (actual amount of Btu/Hr used)
The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support.
You must provide additional fresh air. Your options are as follows:
A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 8.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8.
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.
If the actual Btu/Hr used is less than the maximum Btu/I-lr the space can support, the space is an unconfined space. You will need no
additional fresh air ventilation.
WARNING: Ifthe area In which the heater may beoperated Is smaller than that defined as an unconfined space
or If the building is of unusually tight construction, provide adequate combustion and ventilation air by one of
the methods described in the National Fuel Gas Code, ANS Z223.1, 1992, Section 5.3, or applicable local codes.

C. MOUNTING HEATER WITH
OPTIONAL HEARTH BASE
TO OPTIONAL MANTEL See
instructions included with
mantel kit.
Assembling Mantel
IMPORTANT: Only use the optional man-
tels specified in this manual. See Accesso-
ries, pages 24 and 25 for proper mantel kits.
This heater is only approved for use with
models GMF800(A,B )/GMU801 (A,B),
GMg00F(A,B)/GM901U(A,B), GM700F/
GM701U, GMC22F/GMC23U/GMC24U,
GMC32F(B)/GMC33U(B), and GMC26F/
GMC27U/GMC28F mantel kits. Using any
other mantel will void the A.G.A. approval
for this heater. Do not use models
GMF800(A,B)/GMU80 1(A,B),
GM900F(A,B)/GM901U(A,B), and
GM70OF/GM701U, GMC22F/GMC23U/
GMC24U, GMC32F(B)/GMC33U(B), and
GMC26F/GMC27U/GMC28F mantels with
any other product. Before installing mantel
to heater, the heater must be mounted on the
optional hearth base.
Installing Mantel to Heater
_k WARNING: If installing the
GHB802 or GHB802A base on
heater, and using with a GA se-
ries heater blower accessory
along with a GS601 surround or a
GM800 or GM900 series mantel,
the surround or mantel clearance
to back wall should be 3/4 inch.
This will improve flame appear-
ance and combustion.
Use only a GHB802B, GHB802C,
OR GHB38 series hearth base if
using a GA series heater blower
accessory with a GM70O series,
GMC32F series, or GMC33U se-
ries mantel.
CONNECTING TO GAS
SUPPLY
NOTICE: A qualified service per-
son must connect heater to gas
supply. Follow all local codes.
WARNING: Never connect
heater to private (non-utility) gas
wells. This gas is commonly
known as wellhead gas.
IMPORTANT: Check gas line pressure be-
fore connecting heater to gas line. Gas line
pressure must be no greater than 14 inches
of water. If gas line pressure is higher,
heater regulator damage could occur.
CAUTION : Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of 1/2"
or greater diameter to allow
proper gas volume to heater. If
pipe is too small, undue loss of
pressure will occur.
Installation must include a manual shutoff
valve, union, and plugged 1/8" NPT tap.
Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from
heater (see Figure 20).
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged heater valves.
_k CAUTION: Use pipe ioint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
Install sediment trap in supply line asshown
in Figure 20. Locate sediment trapwhere it
is within reach for cleaning. Locate sedi-
ment trap where trapped matter is not likely
to freeze. Asediment trap traps moisture
and contaminants. This keeps them from
going into heater controls. If sediment trap
is not installed or is installed wrong, heater
may not run properly.
_k CAUTION: Avoid damage to
control. Hold gas fitting with
wrench when connecting ittogas
piping and/or fittings.

ITHERMOSTAT I
CONTROL OPERATION
The thermostatic control used on this
heater differs from standard thermostats.
Standard thermostats simply turn on and
off the burner. The thermostat used on
this heater senses the room temperature.
The thermostat adjusts the amount ofgas
flow to the burner. This increases or de-
creases the burner flame height. At times
the room may exceed the set tempera-
ture. If so, the burner will shut off. The
burner will cycle back on when room
temperature drops below the set tem-
perature. The control knob can be set to
any heat level between HI and LO.
Note:. The thermostat sensing bulb mea-
sures the temperature of air near the
heater cabinet. This may not always agree
with room temperature (depending on
housing construction, installation loca-
tion, room size, open air temperatures,
etc.). Frequent use of your heater will let
you determine your own comfort levels.
MANUAL LIGHTING 1
PROCEDURE
1. Remove front panel (see Figure 2,
page 4).
2. Follow steps 1through 5 under Light-
ing Instructions, page 15.
3. With control knob pressed in, strike
match. Hold match to pilot until pi-
lot lights.
4. Keep control knob pressed in for 30
seconds after lighting pilot. After 30
seconds, release control knob.
5. Replace front panel.
6. Turn control knob counterclockwise
to desired heating level. The
main burner should light. Set control
knob to any heat level between HI
and LO.
INSPECTING
BURNER
Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 25 shows acorrect pilot flame pat-
tern. Figure 26 shows an incorrect pilot
flame pattern. The incorrect pilot flame is
not touching the thermocouple. This will
cause the thermocouple to cool. When the
thermocouple cools, the heater will shut
down.
